Supplementing broilers with fructooligosaccharides (FOS) under stress conditions improves intestinal health by increasing the villus height to crypt depth ratio, boosting Lactobacillus populations, reducing Escherichia coli, and lowering stress levels.
Supplementing broilers with different levels of fructooligosaccharides (FOS) under stress conditions, such as higher stocking densities and recycled litter, showed no significant difference in broiler performance, carcass quality, and meat quality compared to the control group (p>0.05). However, FOS supplementation improved intestinal health by:
- Increasing the villus height to crypt depth ratio.
- Increasing Lactobacillus populations.
- Decreasing Escherichia coli.
- Reducing the heterophil-to-lymphocyte ratio, which indicated lower stress.
Objective
To study the effects of supplementing FOS at two levels (0.2% and 0.5%) in broiler diets under stress conditions on gut microbiota development, production performance, intestinal morphology, stress index, and meat and carcass quality.
To study the effects of supplementing FOS at two levels (0.2% and 0.5%) in broiler diets under stress conditions (high stocking density and recycled litter) on the development of normal gut microbiota, resulting in improved:
- Production performance
- Intestinal morphology
- Stress index
- Meat and carcass quality compared to the non-FOS supplemented group.
